options are MuMu Player Pro for Apple Silicon Macs, which offers a 7-day free trial and then subscription pricing. KOPLAYER does not have evidence of a maintained paid tier or current official distribution.
Windows 11's September update, released on the 8th, has caused various issues, including problems with Remote Desktop, USB audio, and Linux/WSL applications. Failures in File History, crashes of Explorer.exe, and instability with AMD GPUs were also reported. An emergency update was issued on September 14 but did not resolve all issues. Over nine months, Windows 11 updates have resulted in numerous bugs, while Windows 10 has experienced significantly fewer issues. Specific problems with Windows 11 included black screens and authentication issues in January, Microsoft account sign-in issues in March, BitLocker recovery problems in April and May, boot failures in June, and compatibility problems in July. August saw game crashes linked to third-party drivers, and September was marked by extensive issues requiring an emergency update. Windows 10 continues to receive updates and has a commitment to Extended Security Updates until October 12, 2027. The stability of Windows 10 is attributed to fewer significant changes compared to the ongoing enhancements in Windows 11.
Microsoft has rolled out an emergency out-of-band update to address issues from its September Patch Tuesday update, which affected nearly 1,000 vulnerabilities and caused bugs in folder shares on Hyper-V-based Linux virtual machines, Remote Desktop Services sessions, and certain USB audio devices. The new update targets multiple versions of Windows 11 (26h1, 25H2, and 24H2) and also includes updates for Windows Server 2025, 2022, and LTSC versions of Windows 10 and Windows Server 2012 and 2012 R2. In 2023, Microsoft has increasingly issued out-of-band updates, including four in January, two in March, and one in July, to resolve various issues.
On July 14, 2026, Microsoft released cumulative update KB5101650 for Windows 11 versions 25H2 and 24H2, addressing OS Builds 26200.8875 and 26100.8875. This update includes essential security fixes, updates to Secure Boot certificates, and enhanced Remote Desktop Protocol (RDP) defenses against phishing attacks. It consolidates July 2026's security content, addressing known vulnerabilities and introducing functional improvements. The update is critical for minimizing exposure to identified threats and is prioritized for systems managing remote access or nearing certificate expiration.
The update enhances Remote Desktop security by supporting SHA-2 certificate thumbprints while retaining SHA-1 for legacy compatibility. It includes new Group Policy options to mitigate phishing risks associated with malicious .rdp files. The curl upgrade to version 8.21.0 incorporates security patches for command-line tools in Windows environments. Secure Boot certificates are automatically updated through Windows updates, ensuring boot security across various hardware.
KB5101650 installs primarily through the Windows Update interface, requiring a restart to activate changes. Enterprise environments can use the Microsoft Update Catalog for manual distribution. A temporary restriction affects certain Dell devices with Intel Innovation Platform Framework drivers, which Microsoft plans to address in a future update. The cumulative update resolves a total of 622 Microsoft CVEs, including 416 affecting Windows components. Users are advised to verify and install the update promptly to secure the full suite of improvements.
Microsoft has acknowledged a bug in Windows 11 that causes the Capability Access Manager's write-ahead log file to expand indefinitely, potentially exceeding 500GB of storage on affected devices. This issue is addressed in update KB5095093, which includes builds 26200.8737 and 26100.8737. Users can manually install this update via the optional updates section of Windows Update or wait for its automatic rollout during the July 2026 Patch Tuesday. The Capability Access Manager manages app permissions and logs usage of privacy-sensitive features, but the WAL file continues to grow unchecked on affected systems. The file can reach sizes from 70GB to over 513GB. To check if a system is affected, users can check storage settings or use Robocopy to verify the file size. The update is available through the Optional updates section and will be included in the cumulative update on July 8, 2026. The excessive size of the WAL file can lead to critical storage shortages and related issues, but it does not compromise the security or core functionality of the permission system. Microsoft has not confirmed if Windows 11 26H1 Insider builds are affected.
Microsoft is working to improve Windows 11, having started this initiative in late March 2026. Key changes include a customizable Start menu, a repositioned and adjustable taskbar, and a refined widgets board that removes the default MSN feed with ads. Windows search results have been optimized to reduce clutter, and new options allow Home users to delay updates indefinitely, along with bundling updates to minimize reboots. Performance enhancements include faster File Explorer launch speeds, a 'Low Latency Profile' for improved CPU performance, a 'turbo mode' for quicker installations, and a 'Driver Quality Initiative' to enhance OS drivers and reduce battery drain. A point-in-time restore feature has also been introduced. Microsoft is engaging with the Windows community for feedback and has established panels for user testing. However, bugs remain a concern, particularly with the Recycle Bin and storage issues, indicating a need for a stronger quality assurance process. Users have expressed interest in removing intrusive recommendations, installing Windows 11 with a local account, and disabling telemetry in the Home version.
Microsoft resolved an installation issue affecting the June 2026 security updates (KB5094122) on Windows Server 2016 systems that had not previously installed the KB5087537 update, which was a prerequisite. Users had encountered 0x80070002 or FILENOTFOUND errors. Microsoft acknowledged the problem and confirmed that affected devices should no longer experience installation failures for the June 2026 update. Additionally, Microsoft fixed a similar issue with the May 2026 Windows 11 security update (KB5089549) that resulted in 0x800f0922 errors due to insufficient space on the EFI System Partition. They also warned users about potential installation issues with error codes 0x80073712 or 0x800f0993 on devices upgraded to Windows 11 24H2 or 25H2. Furthermore, Microsoft addressed a boot issue for Windows Server 2025 devices after the April 2026 update and a bug affecting installation failures for updates since May 2025 using the Windows Update Standalone Installer (WUSA). Lastly, they are investigating a separate issue preventing third-party applications from launching essential Office programs after the June 2026 updates.
Microsoft is revamping the delivery of updates for Windows 11 by bundling updates for essential components like .NET, drivers, and firmware with the monthly update cycle, currently in testing. The latest preview build (26300.8687) includes improvements to default applications, particularly the Calculator app, which will enhance readability in high contrast themes and fix inaccuracies in square-root calculations. Users will also have the option to delay monthly updates indefinitely to address concerns about update installation failures.
Microsoft resolved an issue causing installation failures and error code 0x800f0922 during the deployment of the May 2026 Windows 11 security update (KB5089549), which was linked to insufficient free space on the EFI System Partition (ESP). The problem mainly affected devices with 10 MB or less available space, leading to automatic rollbacks of the update. The resolution was provided through the release of the Windows 11 KB5089573 preview cumulative update on May 26, 2026. Users installing updates released on or after this date will not need a workaround, while those with earlier updates can use the Known Issue Rollback feature. Additionally, IT administrators in enterprise settings can manually address the issue through Group Policy configurations. The KB5089573 update introduced 30 changes to improve performance and reliability.
